-The only inverter/charger approved by LG for use with the Resu battery is the MultiPlus 48/3000/35. You are **not** able to use these in parallel or three-phase configurations.
+**NOTE - This document is now End-of-Life and for archive purposes only.**
-=== A Venus device is required (either Color Control GX (CCGX) or the VENUS GX) ===
+LG no longer supports the Resu models that were previously compatible.
-It is essential to use the CAN-bus connection of the [[venus-os:start|Venus-device]] with the LG batteries for the keep-alive signal, communication of charge and discharge limits, error codes and state of charge.

 The minimum required firmware version for the [[https://www.victronenergy.com/panel-systems-remote-monitoring/color-control|Color Control GX]] is v2.15. It is highly recommended to use the latest firmware version on all connected devices, including CCGX/VENUS GX, Inverter/Charger and MPPTs. There are regular updates to improve performance and reliability.

   * LG battery policy is to only charge the battery to 97% or 98%. It is normal for the battery not to charge to 100%.

-To use the LG Chem Resu and Victron equipment, it is necessary to use a [[venus-os:start|Venus-device]] (eg CCGX or VenusGX). It takes care of sending the necessary canbus keep-a-live message to the LG Resu. Without it, the LG Resu will open its internal circuitbreaker after 10 minutes.

 ==== Wiring of communication cables ====
-Use the //VE.Can to CAN-bus BMS type B Cable//, part number ASS030720018. Plug the side which is labeled Battery BMS into the LG Chem Resu BMS. Plug the side labeled Victron VE.Can into the [[venus-os:start|Venus-device]].

 Then, plug a [[https://www.victronenergy.com/accessories/ve-can-rj45-terminator|VE.Can terminator]] in the other VE.Can socket on the CCGX. Two VE.Can terminators are included with the package of the CCGX as an accessory, only one is used. Keep the other one as a spare.

 Then:
   - Sustain voltage: 50V
-  - Do not change the dynamic cut-off values, they have already been set correctly after selecting the lithium battery type.
+  - The dynamic cut-off values will effect the depth of discharge you will cycle the battery. The default settings are very safe and conservative, but not optimised for full consumption of battery potential. If you wish to cycle the battery deeper, a flat dynamic cutoff value of 46V allows this system to discharge to the CCGX set SOC limit of 15%, and then a further self-discharge down to ~11% each night. This results in a reported voltage floor of 49.2V by the LG before charging resumes again.

   - Switch the Multis/Quattros on in the CCGX menu. Normal operation should continue after the system has initialized.
